Is AND part of query executed always?

Question

I have a query in SQL Server stored procedure like this:

IF (@EDITED = 1) AND (EXISTS (SELECT 1 FROM InventarizacijaZurnals WHERE RECORD_UNIQUE_ID=@RECORD_UNIQUE_ID)) ....

My question is - will query part after AND always be executed even if first statement is True? I know some languages do it and some doesn't. How does it work in SQL Server? Can't seem to find a clear answer online.

Answer 1

always be executed even if first statement is True

Do you mean first statement is False, not True? When first statement is True we have still possibility that second will be false and then "True and False" is just False. So in that case second query part will be executed.
